| 摘 要： | 本文以单晶碳化钨铸造碳化钨和烧结碳化钨颗粒为陶瓷相，镍基自熔合金为粘结金属，研究了不同种类，粒度和含量的碳化钨颗粒对激光熔覆金属陶瓷层的磨粒磨损性能的影响。结果表明碳化钨颗粒的种类粒度与含量对金属陶瓷激光熔覆层的耐磨性能影响明显，熔覆层耐磨性能随碳化钨含量的变化趋势取决于碳化钨颗粒的种类。

| Abstract: | The abrasive wear resistance of laser clad ceramic-metal composite coatings composed of different kinds, size and weight percent of WC particles has been investigated systematically, in which the single crystal WC, cast WC and cemented WC particles are used as the ceramic phases and Ni-base self-flux alloy as the matrix. The experimental results show that the abrasive wear resistance of the composite coatings is determined by the kinds, sizes, weight fractions of WC particles, and the changing tendency of the abrasive wear resist-ance of the weight fraction of the coatings depends on the type of WC particles. |
